Diagnostic output
Special care must be taken in the printed-circuit board
layout to separate pin 12 from pin 1 and pin 13, to
minimize the crosstalk between the diagnostic output and
the inputs.
Mode select switch
To avoid switch-on plops, it is advised to keep the amplifier
in the mute mode during
>100 ms (charging of the input
capacitors at pin 1 and pin 13).
The circuit in Fig.7 slowly ramps up the voltage at the
mode select switch pin when switching on and results in
fast muting when switching off.
